Theanechanism embodying the invention, as illustrated in Figs. 1.', 2,and 3 of the drawings, comprises a shaft or spindle A having thecircular exterior raceway groove a, a box or case B having in itscylindrical interior the raceway groove b, the rollers C disposedbetween the shaft A and the box B and having the circular racewaygrooves c in the plane of the races a and b, and the balls D which liebetween the parts A and B alternate with the rollers C and are engagedin the raeeway grooves a, I), and c.l The case B is provided with athreaded aperture b1 through which the'balls D are inserted, theaperture being closed by a plug b2 having a raeeway groove 'by formingpart'of the race b. The aperture b1 is provided with the shoulder b* ashoulder b5 of the plug Zf" when the raceway groove section b3 hasreached its proper' position. A screw be is passed into the box and theplug to secure the latter and its raceway groove section in position.

The raceway grooves :of the rollers are so designed and the parts soproportioned that the rolling action of the balls is obsectional viewtaken through the axis of having .my improve- Fig. 2 is. an endeletained by their' contact with the rollers, the
